Description

Technical Field

[0001] This invention relates to the field of air conditioning technology, and in particular to an air conditioner and its sterilization operation control method. Background Technology

[0002] As is well known, bacteria and viruses are not heat-resistant, and the technology of using heating to kill bacteria and inactivate viruses is widely used.

[0003] In recent years, the technology of using ultraviolet light for sterilization has also been gradually applied to air conditioners. Ultraviolet light has a wavelength between 200 and 350 nanometers. By irradiating with ultraviolet light, the molecular structure of the DNA (deoxyribonucleic acid) or RNA (ribonucleic acid) of microorganisms is destroyed and altered, causing bacteria to die immediately or be unable to reproduce, thus achieving the purpose of sterilization.

[0004] The ultraviolet sterilization devices in existing air conditioners are usually LED ultraviolet lamps. After continuous and long-term operation, their luminous efficiency will decrease or they may even fail to operate normally, which will lead to a decrease in the sterilization efficiency of the sterilization module or an inability to effectively sterilize. Summary of the Invention

[0005] To address the aforementioned problems, the first objective of this invention is to provide a sterilization operation control method that extends the lifespan of the ultraviolet light source without reducing the sterilization and inactivation effects of the ultraviolet sterilization module. The second objective of this invention is to provide an air conditioner that applies the aforementioned sterilization operation control method.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] An air conditioner and its sterilization operation control method are disclosed. The air conditioner includes a controller, an indoor unit, and an outdoor unit. Its features include:

[0008] The indoor unit includes an indoor heat exchanger, an ultraviolet sterilization module, an indoor fan, an indoor ambient temperature sensor, and a heat exchanger temperature sensor; the ultraviolet sterilization module can generate ultraviolet rays that irradiate the air passing through the surface of the indoor heat exchanger.

[0009] The indoor unit and the outdoor unit form a loop through the first refrigerant connection pipe and the second refrigerant connection pipe;

[0010] The control method steps are as follows:

[0011] S1: The air conditioner starts operating after obtaining the user's set parameter information. The controller determines whether the user has turned on the sterilization function. If the sterilization function is turned on, the controller continues to determine whether the current operating mode is the heating mode. If the current operating mode is the heating mode, the controller obtains the indoor ambient temperature Ti and the indoor heat exchanger temperature Te, and obtains the h value based on the values ​​of Ti and Te.

[0012] S2: Set the temperature judgment threshold 'a'. The controller compares the acquired Te value with 'a'.

[0013] If Te > a, set the time statistics parameter t = 0, and at the same time, the controller controls the ultraviolet sterilization module to pause output;

[0014] If Te≤a, during the statistical time t, the controller controls the ultraviolet sterilization module to output at low power and operate in mode 1.

[0015] S3: In S1, if the air conditioner is in non-heating mode, the controller determines whether the current operating mode is air supply mode. If the current operating mode is air supply mode, the controller obtains the indoor ambient temperature Ti and obtains the f value based on the Ti value; after a statistical time t, the controller controls the ultraviolet sterilization module to output at medium power and operate in mode 2.

[0016] S4: If the air conditioner is in non-heating and non-fan mode, during the statistical time t, the controller controls the ultraviolet sterilization module to output at high power and operate in mode 3.

[0017] Preferably, in S2, after the ultraviolet sterilization module pauses output, it counts time t, sets a time judgment threshold c, compares the time statistics parameter t with the preset threshold c, and if t≥c, sets X=0, sets t=0, and returns to S1; if t<c, it continues to count time until t≥c.

[0018] Preferably, in S2, the ultraviolet sterilization module operates in mode 1, comparing the time statistics parameter t with the preset threshold b. If t ≥ b, X = 1, then the time statistics parameter t = 0, and the ultraviolet sterilization module pauses output. If t < b, and the user has not adjusted the air conditioner parameters, return to S2.

[0019] Preferably, in S3, the ultraviolet sterilization module operates in mode 2, comparing the time statistics parameter t with the preset threshold b. If t ≥ b, X = 1, then the time statistics parameter t = 0, and the ultraviolet sterilization module pauses output. If t < b, and the user has not adjusted the air conditioner parameters, the time t is re-statisticalized.

[0020] Preferably, in S4, the ultraviolet sterilization module operates in mode 3, and the user does not adjust the air conditioner parameters. The time statistics parameter t is compared with the preset threshold b. If t ≥ b, the time statistics parameter t = 0, and the sterilization module pauses output. If t < b, the time t is counted again, and the ultraviolet sterilization module outputs at high power.

[0021] Preferably, the controller includes an indoor control mechanism and an outdoor control mechanism that can communicate with each other and control the indoor unit and the outdoor unit respectively.

[0022] Preferably, the indoor control mechanism includes a user information receiving module, an operation information acquisition module, an operation status judgment module, an operation status control module, and an information storage module; wherein:

[0023] The user information receiving module is suitable for obtaining the air conditioner operating status information set by the air conditioner user.

[0024] The operation information acquisition module is suitable for acquiring information on the ambient temperature of the space where the indoor unit of the air conditioner is located and the temperature of the indoor heat exchanger.

[0025] The operation status judgment module is suitable for judging the operation status of the air conditioner's ultraviolet sterilization module based on the information received by the air conditioner.

[0026] The operation status control module is suitable for controlling the operation status of the air conditioner's ultraviolet sterilization module based on the operation status information provided by the operation status judgment module.

[0027] The information storage module is suitable for storing operating information during the operation of the air conditioner.

[0028] An air conditioner, characterized in that it is applied to any one of the above-mentioned air conditioners and its sterilization operation control method.

[0029] This invention employs the above-mentioned technical solution to provide a sterilization operation control method. This method can control the output power and output time of the ultraviolet sterilization module according to the indoor ambient temperature, indoor heat exchanger temperature, and operating mode. When the indoor ambient temperature or indoor heat exchanger temperature is high, the output of the ultraviolet sterilization module is reduced, and vice versa. Under the premise of ensuring sterilization effect, this method can effectively prevent premature aging of the ultraviolet sterilization module and increase its service life.

[0030] Specifically, this solution can determine the sterilization conditions based on factors such as indoor ambient temperature, indoor heat exchanger temperature, and operating mode, and control the UV sterilization module to output intermittently or continuously. When the sterilization conditions are good (high ambient temperature, heating mode, high heat exchanger temperature), the UV sterilization module is controlled to output intermittently. When the sterilization conditions are average (such as air supply mode), the UV sterilization module is controlled to output intermittently (the stop time is shorter than that in heating mode). When the sterilization conditions are poor (such as dehumidification mode, cooling mode), the sterilization module is controlled to output continuously. Attached Figure Description

Example 1:

[0042] like Figures 1-2 An air conditioner 1 shown includes a controller, an indoor unit 10, and an outdoor unit 20;

[0043] The indoor unit 10 includes an indoor heat exchanger 101, an ultraviolet sterilization module 102, an indoor fan 103, an indoor ambient temperature sensor 104, and a heat exchanger temperature sensor 105; the ultraviolet sterilization module 102 can generate ultraviolet rays to irradiate the air passing through the surface of the indoor heat exchanger 101.

[0044] The indoor unit 10 and the outdoor unit 20 form a circuit through the first refrigerant connection pipe 30 and the second refrigerant connection pipe 40;

[0051] The information storage module 1065 is suitable for storing operating information during the operation of the air conditioner. Example 2:

[0052] like Figures 3-6 The steps of the sterilization operation control method shown are as follows:

[0053] S1: The air conditioner starts operating after obtaining the user's set parameter information. The controller determines whether the user has turned on the sterilization function. If the sterilization function is turned on, the controller continues to determine whether the current operating mode is the heating mode. If the current operating mode is the heating mode, the controller obtains the indoor ambient temperature Ti and the indoor heat exchanger temperature Te, and obtains the h value based on the values ​​of Ti and Te.

[0054] S2: Set the temperature judgment threshold 'a'. The controller compares the acquired Te value with 'a'.

[0055] If Te > a, set the time statistics parameter t = 0, and at the same time, the controller controls the ultraviolet sterilization module to pause output;

[0056] If Te≤a, during the statistical time t, the controller controls the ultraviolet sterilization module to output at low power and operate in mode 1.

[0057] S3: In S1, if the air conditioner is in non-heating mode, the controller determines whether the current operating mode is air supply mode. If the current operating mode is air supply mode, the controller obtains the indoor ambient temperature Ti and obtains the f value based on the Ti value; after a statistical time t, the controller controls the ultraviolet sterilization module to output at medium power and operate in mode 2.

[0058] S4: If the air conditioner is in non-heating and non-fan mode, during the statistical time t, the controller controls the ultraviolet sterilization module to output at high power and operate in mode 3.

[0059] Furthermore, in S2, after the ultraviolet sterilization module pauses output, it counts time t, sets a time judgment threshold c, and compares the time statistics parameter t with the preset threshold c. If t≥c, it sets X=0, sets t=0, and returns to S1; if t<c, it continues to count time until t≥c.

[0060] Furthermore, in S2, the ultraviolet sterilization module operates in mode 1, comparing the time statistics parameter t with the preset threshold b. If t ≥ b, X = 1, then the time statistics parameter t = 0, and the ultraviolet sterilization module pauses output. If t < b, and the user has not adjusted the air conditioner parameters, it returns to S2.

[0061] Furthermore, in S3, the ultraviolet sterilization module operates in mode 2, comparing the time statistics parameter t with the preset threshold b. If t ≥ b, X = 1, then the time statistics parameter t = 0, and the ultraviolet sterilization module pauses output. If t < b, and the user has not adjusted the air conditioner parameters, the time t is re-statisticalized.

[0062] Furthermore, in S4, the ultraviolet sterilization module operates in mode 3, and the user does not adjust the air conditioner parameters. The time statistics parameter t is compared with the preset threshold b. If t ≥ b, the time statistics parameter t = 0, and the sterilization module pauses output. If t < b, the time t is counted again, and the ultraviolet sterilization module outputs at high power.

[0094] Symbol explanation:

[0095] Ti: Indoor ambient temperature, in °C;

[0096] Te: Indoor heat exchanger temperature, in °C;

[0097] a: Preset temperature threshold, in °C, e.g., a is preset to 55 °C;

[0098] b: Preset time threshold, such as b is preset to 10 minutes;

[0099] c: Time threshold, in minutes, e.g., c is preset to 5 minutes;

[0100] t: Time statistics parameter, in minutes;

[0101] h: The operating coefficient of the ultraviolet sterilization module in the heating mode, with a value range of 0-1;

[0102] f: Operation coefficient of ultraviolet sterilization module in air supply mode, with a value range of 0-1;

[0103] X: Marker symbol, X=0 or X=1; (The controller marks (X=1) after the LED has been running continuously for a period of time, and counts the time during X=1. During X=1, the LED will not be put into operation to avoid the LED running for a long time and the output efficiency will decrease rapidly) (X=0, the LED can continue to output).

[0104] In addition, Mode 1 is the sterilization mode under heating, Mode 2 is the sterilization mode under air supply, and Mode 3 is the sterilization mode under cooling or dehumidification mode (in non-heating and air supply modes).

[0105] like Figure 6 As shown, the ultraviolet sterilization module involved in this invention can switch between multiple output modes:

[0106] 1. Continuous output, such as Figure 6 The continuous output scheme shown above operates with the ultraviolet sterilization module outputting at high power during continuous output.

[0107] 2. Intermittent output: Within a working cycle, the ultraviolet sterilization module can output intermittently at a uniform power or at different power levels.

[0108] like Figure 6 As shown in intermittent output scheme 1, the ultraviolet sterilization module operates at a coefficient of 0.2 and outputs at low power.

[0109] like Figure 6 As shown in the intermittent output scheme 2, the ultraviolet sterilization module operates at a coefficient of 0.4 and outputs at medium power.

[0110] like Figure 6 As shown in the intermittent output scheme 3, the ultraviolet sterilization module operates at a medium power output with an operating coefficient of 0.4 for a period of time, and then switches to a low power output with an operating coefficient of 0.2.

[0111] The above output modes are just examples. In actual work, the output coefficient, output power or output can be dynamically adjusted or stopped according to the sterilization situation.

[0112] In this specific embodiment, the ultraviolet sterilization device in existing air conditioners is usually an LED ultraviolet lamp. After continuous and long-term operation, its luminous efficiency will decrease or it may even fail to operate normally, which will lead to a decrease in the sterilization efficiency of the sterilization module or an inability to effectively sterilize. The above solution can control the output power and output time of the ultraviolet sterilization module according to the indoor ambient temperature, indoor heat exchanger temperature, and operating mode. When the indoor ambient temperature or indoor heat exchanger temperature is high, the output of the ultraviolet sterilization module is reduced, and vice versa. Under the premise of ensuring the sterilization effect, it can effectively prevent the ultraviolet sterilization module from aging prematurely and increase the service life of the ultraviolet sterilization module.

[0113] Specifically, this solution can determine the sterilization conditions based on factors such as indoor ambient temperature, indoor heat exchanger temperature, and operating mode, and control the UV sterilization module to output intermittently or continuously. When the sterilization conditions are good (high ambient temperature, heating mode, high heat exchanger temperature), the UV sterilization module is controlled to output intermittently. When the sterilization conditions are average (such as air supply mode), the UV sterilization module is controlled to output intermittently (the stop time is shorter than that in heating mode). When the sterilization conditions are poor (such as dehumidification mode, cooling mode), the sterilization module is controlled to output continuously.

[0114] The ultraviolet sterilization module outputs low power in heating mode, medium power in air supply mode, and high power in non-heating and non-air supply mode.

[0115] The ultraviolet sterilization module can be continuously or periodically put into operation during its operating cycle.

[0116] During heating operation, the operation mode of the ultraviolet sterilization module can be controlled according to the indoor ambient temperature and the indoor heat exchanger temperature. The ultraviolet sterilization module can output continuously or intermittently.

[0117] If the indoor heat exchanger temperature is too high during heating operation, the ultraviolet sterilization module will stop outputting.

[0118] During the air supply operation, the operation mode of the ultraviolet sterilization module can be controlled according to the indoor ambient temperature. The ultraviolet sterilization module can output continuously or intermittently.

[0119] During operation without heating or air supply, the ultraviolet sterilization module continuously outputs UV sterilization.

[0120] After continuous operation, the ultraviolet sterilization module can be stopped for a period of time to avoid a rapid decrease in output efficiency caused by prolonged operation of the ultraviolet sterilization lamp.
